ENOGH PHELPS, OF WESTFIELD, MASSACHUSETTS.

WH'lP-COUPLING.

SPECIFICATION forming part of Letters Patent No. 277,778, dated May 15,1883.

Application tiled March 29, 1883. (No model.)

To all whom it may concern:

Be it known that I, ENocH PHELPs, a citizen of the United States ofAmerica, residing at Westfield, in the county ofHampden and State ofMassachusetts, have invented certain new Aand useful Improvements inWhip-Couplings;

and I do hereby ticolare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and -t-o letters or figures ot' referencemarked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements inwhip-couplings; and it has for its object to provide a joint theeXterior surface of which will be plain or smooth, and which is providedon its interior with a screwthread, 'which is formed by insertingtherein a spiral wire and solderingthe same to the casing, as will behereinafter more fully set forth, and pointed out in the claim.

In the annexed drawings, which illustrate my invention, Figure l is aView showing my improved whip-coupling applied. Fig. 2 is a longitudinalsection.

1n the annexed drawings, which illustrate my invention, A represents atube, which is cylindrical in shape. This tube is preferably made ofspun metal, and, having av smooth eX- terior, is adapted to receiveornamentation. The interior of the tube A is provided with a wire, B,which is bent spirally, and secured within the tube by means oi'solder.The ends of this wire, which terminate near the end of the tube, aresharpened. By this means the interior of the tube is provided with ascrewthread which does not show on the exterior, which is objectionablein high-priced whips.

I am aware that prior to myinvention whipcouplings which consist of asheet-metalsleeve having a thread spun upon the salme have beenconstructed; but this construction, for the reason aforesaid, isconsidered objectionable. Whip-couplings have also been constructed ofwire which has been coiled and braced upo 'tselwhich formsascrew-threadedinterior au exterior; and I do not claim such as myinvention, my invention being especially designed to obv^`iate theobjection set forth by the trade to the aforesaid style ot' cou pl i ng.

The coupling hereinbefore described maybe cheaply manufactured, as thesleeve is made of spun metal.- The screw-threadedinterior of the sleeveserves to hold the parts ofthe whi p firmly and securely together.

Having thus described my invention, what I claim as new, and desire tosecure by' Letters Patent, is

The sheet-metal coupling for whips having a plain exterior, and providedon its interior with ascrew-thread form ed by a spirally-curved wire,which is secured to the interior of the sleeve throughout its wholelength, substantially as described, and for the purpose set forth. i

In testimony whereof I affix my signature in presence of .two witnesses.
